REST DSS ISIN to RIC for specific exchange

petr.synek

Hi,

I'm using .NET DSS REST example Tutorial 8 restful_api_TandC.sln to translate ISIN to RIC using the TermsAndConditionsExtractionRequest.

When I specify the instrument without using the Source field:

new InstrumentIdentifier {Identifier = "ZAE000097580", IdentifierType = IdentifierType.Isin}

It correctly returns RIC "SUIJ.J". However when I try to specify also the Exchange Code for the Johannesburg exchange "JSE" in the Source field I get no results:

new InstrumentIdentifier {Identifier = "ZAE000097580", IdentifierType = IdentifierType.Isin, Source = "JSE"}

Do you know why specifying the exchange code in the Source field doesn't work? AFAIK the "JSE" exchange code should be correct. Thanks for any hint.

petr.synek, ISIN ZAE000097580 effectively corresponds to RIC SUIJ.J, but the exchange code is JNB, not JSE.

To find this out, you can make the request without the source, and:

• Include field "Exchange Code" in the output; it will deliver the primary exchange, which is JNB.
• Include field "Exchange Code List" in the output; it will deliver the list of exchanges where it is traded: JNB and BER.

Hi Hristiaan,

Thanks for your response. You are true, the proper code is JNB.

Do you know where can I find list of all exchange codes? What I've found so far is that the Johannesburg exchange was always referenced as JSE.

petr.synek, look at the DSS
Data Content Guide, appendix F, this can help.

In the screenshot below I filtered column B to display entries that contain "Johannesburg". There we see that most instruments are quoted on JNB. JSE is only for CFDs:

Great, thanks!
